PUTTYLESS STEEL SKYLIGHT.

Application filed December 13, 1918.

To all whom it may concern:

Be it known that I, LOUIS Fnnrzsonnrem), J12, a citizen of the United States, residing at New York city, county and State of New York, have invented new and useful Improvements in Puttyless Steel Skylights, of which the following 1s a full, clear, and exact specification.

My invention relates to puttyless skylights such as are used on the roofs of buildings for example and an obgectthereof is to provide a skylight which will not only be water-proof at all times but of maximum strength as well and one requiring but the minimum material and time for production. i

A further object of my lnvention 1s the provision of a skylight which w1ll be of sufficient strength to support workmenon the bars thereof when the skylight 1s be ng erected or repaired, the danger of breakmg of the glass of the skylight or stralning any parts thereof either in erectlon or 1n making repairs, being practically ellm nated.

In the accompanying drawings illustrating an embodiment of my invent1on,-

Figure 1 shows my improved skylight in plan;

Fig. 2 is an end View of the same Fig. 3 is a section taken on the line 3-3 of Fig. 1; t

Fig. 4 is a view taken on the hue 44 of Fig. 3;

Fig. 5 is an elevation of the ends of the eaves showing a stop employed 1n the pres ent structure; and

Fig. 6 is a perspective of the glass-supporting bar employed.

Referring to the drawings in detail, 1 designates a glass-support1ng bar preferably of rolled steel, th1s bar bemg provlded with lateral and oppositelyextendlng base portions 2 and 3 for rece1ving glass-supporting cushions 4- of asbestos for example. The bar is also provided with condensation gutters 5 at the outer edges of the base portions 2 and 3 already referred to.

The top of the bar 1 is provided w1th a sheet-metal ridge 6 secured thereto at suitable intervals by bolts 7. Secured to but spaced from the sides of the bar 1 by bolts 8 are caps 9 and 10 each of wh ch 1s provided with ofl'setor lateral extenslons adapted to be overlapped by outwardly-extendmg Specification of Letters Patent.

portions 11 and 12 respectively, of the metal ridge 6 as will be hereinafter pointed out. The lower edges of the caps 9 and 10 are in the present instanceturned inwardly substantially at right angles to the face of the member 1 when the parts are assembled as indicated at 13 and 14;, these portions 13 and 14 resting upon non-absorbent asbestos cush- 1011s 15 and 16 placed between the portions 13 and 14 of the caps 9 and 10 and the glass 17 of the skylight. It will be seen, therefore, that when the parts are assembled as shown in Fig. 4 for example the glass 17 is in effect yieldingly retained in position in the skylight confined between the base portions 2 and 3 of the bar 1 and the asbestos cushions 4.- on the one hand and the cushions 15 and 16 and the portions 13 and 14 on the caps 9 and 10 on the other.

The purpose of the construction thus far described is to take up the compression stresses in the skylight, the upward thrust of the metal caps 9 and 10 when the bolts 8 are set up being taken up by the lower outwardly-extending portions 11 and 12 of the cap 6. It will be understood that when the parts are assembled and the bolts 8 are set up the caps 9 and 10 are free to yield centrally to cause the upper edges of the caps underlying the lower'edges11 and 12 of the cap 6 to become properly seated, the lower and inwardly-extending portions 13 and 14. of the caps 9 and 10 resting firmly and securely on the cushions 15 and 16 to securely bind the glass 17 and insuring a firm and watertight connection at this point petfiveen the caps and the glass of the sky The eaves of the skylight are also novel in construction as will be seen from Fig. 3, being provided with an adjustable apron 18 which provides a gutter 19 and clip 20, the latter being attached to the end of the bar 1 in any suitable manner. The apron 18 is provided with an asbestos cushion 21 drawn up to the under side of the glass of the skylight, the glass at this point being securely held or clamped in place between the clip 20 and the oliset portion 22 of the apron 18 by adjustable bolts 23,. the clip 20 being provided with a downwardly-extending portion 24- overlapping or overlying the end of the glass and functioning as a stop therefor.

By the construction described ample support is provided for the glass as well as a uniform one so that in assembling the skylight there is no danger of breaking the glass thereof and this construction.. also insures .a thorough waterproof condition at all times. 7

From the foregoing it will be seen that in the construction of my improved skylight the glass issecurely held in position at all times. and the endsof the glass-supporu ingbars are closed in' and the caves of the skylight are water-proof by means 'ofthe adjustable apron 18 and the clip 20 so that a weather-proofconditionof the skylight is assured at all times It will be apparent furthermore that by providing the metal ridge 6 and the caps 9 and 10 breakage of the glass dueto contractionand expansion thereof will be eliminated inasmuch as by reason of'the particular manner in which the glass of my improved skylight is held in place the same may contract and expand without breaking the glass and in repairing the skylight planks or other supportsmay be placed across the bars 1 and the skylight repaired without breaking the glass of the skylight or subjecting the same to undue strain. 1 Iaving thus described my invention, what I claim as new and desire to secure by Letters Patent of the United Statesis':

1. The combination with a glass support ing bar'for skylights having an upwardly extending rib and'oppositely extending base portions, of cushions on said base portions, glass seated on said cushions, upper cushions above the glass, and caps covering the opposite sides of the rib andhaving outwardly extending portions, downwardly inclined portions at the outer edges of said outwardly extend ng portions and spaced away from the rib, and inwardly extending portions at the lower edges of said mcllned portions to engage said upper cushions.

2. The combination with a glass supporting bar for skylights having an upwardly extending rib and oppositely extending base portions, of glass supported on said base portions, caps secured to the opposite sides of the rib and having outwardly and downwardly inclined portions at their upper edges, the lower edge portions of said caps servingtohold the'glass down on the base portions of the bar, and a separate'ridge member secured .over the upper edge of the rib and having inclined marginal portions fitting and overlapping the inclined upper edges of the caps to prevent theirupward movement.

3. In a skylight the combination of a glass-supporting bar, caps secured thereto and adapted toyieldingly clamp the glass of the skylightto the bar, a portion of the bar 'side opposite theclip. '7 V '5. In skylight the'combination 'of a glass-supporting bar,,a clip secured thereto and providing a stop for the glass of vthe skylight, and an adjustable apron secured to said clip and cooperating therewith to weatherproof the eaves of. the skylight.

In testimony whereofI have signed. my

name to this specification.
